Compact M3 - M5 tap handles for tapping holes in 3D prints (I don't think they're strong enough for tapping metal -- actually it works fine). I find them to be more convenient than the larger metal tap handles when working with plastic.
The M3 and M3 versions use 35mm M5 screws, the M5 version uses 40mm M5 screws. The holes for these screws should be tapped before adding the side screws to avoid splitting the plastic.
